What Fire Extinguishers Does My HMO Need?
The answer is not as straightforward as most landlords expect. Fire extinguishers are not an automatic legal requirement in HMOs, but that does not mean you do not need them — and getting this wrong in either direction carries real risk.
It is one of the questions we hear most often from HMO landlords, particularly those who are preparing for a licensing inspection or have just taken on a new property and are working through their fire safety obligations for the first time. The assumption is usually that the answer will be simple — a prescribed number of extinguishers in prescribed locations — but the reality is more nuanced than that, and the nuance matters because it affects both the safety of your tenants and your position with the licensing authority.
The starting point, as it is for almost every fire safety question in a non-domestic or HMO setting, is the fire risk assessment.
How Quickly a Kitchen Fire Can Develop
Before addressing what equipment an HMO requires, it is worth understanding why kitchens are treated as the principal risk area in shared residential properties. More than half of all house fires in the UK start in the kitchen, and the footage below — captured on home cameras in the United States, where interior cameras are more common than in the UK — illustrates the speed with which a small cooking incident can become a serious fire. We are not endorsing the responses shown, and UK fire safety guidance is clear that occupants should not attempt to fight a fire that has developed beyond its very earliest stage. The videos are included because they demonstrate, more vividly than any written description can, why early detection, proper firefighting equipment, and clear evacuation procedures all have to be in place before the moment they are needed.
Both videos are from the United States, where interior home cameras are more widely used than in the UK. They are included here as illustrative material only. Fletcher Risk Management does not endorse the actions shown — UK fire safety guidance is that occupants should get out, call 999, and stay out unless a fire is very small and in its earliest stage, the exit behind them is clear, and they have been trained in the correct use of the equipment to hand.
The Legal Position: What the Regulatory Reform (Fire Safety) Order Actually Says
The Regulatory Reform (Fire Safety) Order 2005 applies to the common parts of HMOs — the hallways, stairwells, landings, shared kitchens, and any other communal areas — and places a duty on the responsible person, which in most cases is the landlord or the managing agent, to carry out a suitable and sufficient fire risk assessment and to implement the preventive and protective measures it identifies. The Order does not prescribe a fixed list of equipment that every HMO must have. It requires that risk is assessed and that appropriate measures are put in place in response to that assessment.
Fire extinguishers are not, therefore, an automatic legal requirement in an HMO. There is no regulation that states every HMO must have one extinguisher per floor or one extinguisher in every kitchen. What the law requires is that the responsible person assesses the fire risks in their specific property and provides whatever firefighting equipment the assessment identifies as necessary. In many HMOs, a thorough fire risk assessment will conclude that extinguishers are appropriate, particularly in common areas and kitchens. In others, it may conclude that they are not warranted, or that the risks associated with providing them — including the risk that an untrained occupant will attempt to fight a fire rather than evacuate — outweigh the benefits.
Some local authorities take a more prescriptive approach through their HMO licensing conditions, and it is worth checking with your local housing team or speaking with a fire risk assessor who knows the requirements in your area, because what Cheshire West and Chester Council expects may differ in emphasis from what another authority requires.
The key principle: The fire risk assessment drives the requirement. If a competent assessor concludes that your HMO needs fire extinguishers, you need them. If the assessment concludes they are unnecessary or counterproductive for your specific property and tenant profile, that conclusion — properly documented — is your defence if the question is ever raised by an inspector.
What you cannot do is simply decide for yourself, without a proper assessment, that extinguishers are or are not required. The assessment must be carried out by a competent person, and it must be kept up to date.
Fire Blankets: A Different Matter Entirely
While extinguishers are not universally prescribed, fire blankets occupy a different position. Every shared kitchen in an HMO, and every bedroom that contains cooking facilities, should have a wall-mounted fire blanket, and this is a requirement that most licensing authorities will enforce consistently. Fire blankets are inexpensive, require no training to use effectively, do not require annual servicing, and address the most common source of fire in any residential property — the cooker. A frying pan fire, caught early with a fire blanket deployed correctly, is contained before it becomes a structural fire. Without one, the same incident has a straightforward path to a serious outcome.
The blanket should be mounted on the wall in a position that does not require the occupant to reach across the cooker to access it — ideally beside the cooker rather than above it — and it should be checked periodically for damage to the packaging or the release mechanism. A fire blanket that has been used, or whose packaging has been compromised, must be replaced. This is a straightforward maintenance obligation that is nonetheless frequently overlooked, particularly in properties that turn over tenants regularly.
When Extinguishers Are Appropriate: What the Assessment Should Consider
The fire risk assessment for an HMO will consider a range of factors in deciding whether portable firefighting equipment is warranted, and if so, what type and where. The principal considerations are the size and layout of the property, the nature and profile of the occupants, the fire risks present in each part of the building, and the likely behaviour of occupants in an emergency.
For larger HMOs — properties with five or more occupants — it is generally considered good practice to provide at least one suitable extinguisher on each floor in the common parts, and LACORS fire safety guidance, which most local authorities follow as a baseline, supports this approach. For smaller HMOs, the picture is more variable. Some assessors will recommend a single extinguisher in the shared kitchen; others, particularly where the occupant profile suggests a higher risk of misuse, will conclude that the priority is getting people out rather than giving them the means to attempt to fight a fire.
The concern about misuse is not theoretical. An occupant who picks up an extinguisher rather than evacuating, uses the wrong type on the fire in front of them, or depletes the extinguisher without suppressing the fire, is now in a worse position than if there had been no extinguisher at all. This is one reason why tenant education — making sure occupants know where the extinguishers are, what they are for, and, critically, that they should only attempt to use one on a very small fire in the early stages and only if the exit behind them is clear — forms part of the responsible person's duty under the Fire Safety Order. Fire safety training for occupants need not be elaborate, but it should be documented.
Which Type of Extinguisher for an HMO?
If the fire risk assessment concludes that extinguishers are required, the next question is which type. This matters more in an HMO than in most commercial settings, because the range of people who might use them is unpredictable and the consequences of using the wrong type on the wrong fire can be severe. The general principle for HMOs is to select a single type of extinguisher that is suitable for the range of fire risks likely to be present, rather than providing multiple types that require occupants to identify the correct one under stress.
| Type | Suitable fires | HMO suitability |
|---|---|---|
| Water mist | Class A (wood, paper, fabric), Class B (flammable liquids), electrical equipment | Generally the best all-round choice for HMO common areas. Safe on most domestic fire risks including electrical, does not leave residue. Available in service-free variants (P50) which reduce ongoing maintenance costs. |
| Foam (AFFF) | Class A and Class B fires | A reasonable choice where electrical risk is low. Not suitable for use on live electrical equipment. Leaves residue requiring clean-up. |
| CO2 | Electrical fires, Class B | Suitable as a secondary extinguisher near electrical panels or server rooms, but not recommended as the primary provision in communal living areas. Provides no cooling effect — fire can re-ignite. |
| Dry powder | Class A, B, C and electrical | Multi-purpose but creates significant mess, reduces visibility, and can cause respiratory problems in enclosed spaces. Generally not recommended for indoor HMO use despite its broad coverage. |
| Wet chemical | Class F (cooking oils and fats) | The correct choice if a kitchen extinguisher is specified and the primary risk is deep-fat frying or chip pan fires. Should not be used as the sole provision — combine with a fire blanket. |
Water mist extinguishers have become the preferred recommendation for most HMO common areas precisely because they cover the majority of risks a domestic occupant is likely to encounter — including electrical fires — without requiring the user to make a risk classification decision in the heat of the moment. The P50 service-free variant also removes the annual servicing obligation that adds ongoing cost to traditional steel extinguishers, which require engineer inspection in accordance with BS 5306-3 every twelve months and replacement or discharge testing at five years.
Placement and Maintenance
Where extinguishers are provided, their placement should follow from the fire risk assessment rather than from a general rule of thumb, but the practical principle is that an extinguisher should be accessible from the escape route without requiring someone to pass through the area of greatest fire risk to reach it. In a multi-storey HMO, one extinguisher per floor on the landing or in the stairwell is a common arrangement. In a property where the kitchen is the principal risk area, an additional extinguisher or fire blanket in or adjacent to the kitchen may be appropriate alongside the provision on the landing.
Maintenance obligations apply regardless of type. Traditional extinguishers must be inspected annually by a competent person in line with BS 5306-3, and the inspection record must be kept. They must be replaced or subjected to a discharge test at five years. Extinguishers that have been used, even partially, must be replaced or recharged before being returned to service. The responsible person should also carry out periodic visual checks between annual services — checking that the extinguisher is in its designated location, that the safety pin and tamper seal are intact, and that the pressure gauge (where fitted) shows within the operating range. These checks should be documented as part of the fire safety management record for the property.
An extinguisher that is out of date, damaged, missing its pin, or simply not in the location shown on the fire safety plan is not merely useless — it creates a false sense of security and, if discovered during a licensing inspection, will reflect poorly on the responsible person's overall standard of fire safety management. Fire door inspections and extinguisher maintenance sit alongside each other as the kind of routine, documented obligation that separates a properly managed HMO from one that is compliant on paper and deficient in practice.
The Relationship Between Extinguishers and the Wider Fire Safety System
It is worth being clear about what fire extinguishers are and are not. They are a means of tackling a small fire in its very early stages, before it has had the opportunity to develop, and only where doing so does not put the person using them at risk. They are not a substitute for a working fire detection system, properly maintained fire doors, clear and unobstructed escape routes, and occupants who know what to do when the alarm sounds. The fire safety system in an HMO is a set of interdependent components, and a well-specified extinguisher in a property with compromised fire doors and a poorly maintained alarm system does very little to protect the people inside.
The fire risk assessment is the document that ties these components together, identifies the gaps, and sets out what the responsible person must do to address them. For HMO landlords who are uncertain about their current position — whether they need extinguishers, whether the ones they have are the right type, or whether their overall fire safety arrangements are adequate — the assessment is the correct starting point, and it is a legal obligation rather than an optional exercise.
In summary:
Fire extinguishers are not a universal legal requirement in HMOs, but your fire risk assessment may well require them, particularly in larger properties and shared kitchens. Fire blankets in all shared kitchens and bedrooms with cooking facilities are expected as standard. Where extinguishers are provided, water mist is generally the most appropriate type for communal areas. All firefighting equipment must be maintained, documented, and supported by tenant information on correct use. The fire risk assessment is the legal and practical foundation for all of these decisions.
